TO F. M. BENNETT AND J. L. HALL, OF EMMA, MISSISSIPPI.

PLOW.

SPECIFICATION forming part Of Letters Patent No. 697,389, dated. April8, 1902.

Application filed August 15, 1901. Serial No. 72,164. (No model.)

To all whom it may concern:

Be it known that LJAMES PINKNEY BARNES,

a citizen of the United States, residing at combinations and changes maybe easily and expeditiously made, so as to adapt the plow for thevarious kinds of work to be done on a farm, and at the same time theshovels re tain a true parallelism with respect to each other and withrespect to the plow-beam or line of draft, so that the plow-points,cultivator-shovels, or the tilling blade or implement used will alwaysbe in proper position with respect to the line of draft, and therebymore readily pass through the soil.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularly pointedout in the appended claim.

In the accompanying drawings, Figure l is aperspective view of myimproved plow,showing the plow-standards arranged in a horizontal lineat right angles to the beam and parallel with each other; and Fig. 2 isa similar View showing the plow-standards arranged in a line diagonal tothe beam, with the cultivator-shovels parallel with the line of draftand with each other.

In the drawings, 1 denotes a plow-beam, and 2 the handles.

3 denotes the forward set of cross-bars pivoted to the plow-beam, and 4the rear set of cross-bars pivoted to the plow-beam.

5 denotes links pivoted between the ends and connecting the front andrear set of crossbars.

6 denotes standards, three being shown in the present instance, twobeing connected to ments to the standards.

the links and one being connected to the beam. Each plowstandardconsists of a doubled piece of metal, the upper ends of which are spreadapart and lie against the sides of the links and the sides of theplow-beam. Bolts 11 connect the ends of the plow-standards above thelinks and plow-beam and bolts 12 connect them below the links andplow-beam, whereby the tendency of the plow-beam to be forced downwardwhen the plow strikes an obstruction or the tendency of the plow-beam tobe forced upward are resisted, thus producing a strong construction.

6 denotes braces connecting the plow-standards to the rear ends of thelinks.

'7 denotes a segmental bar pivotally connected to the forward ends ofthelinks and provided with a row of apertures 8, through any one of whichis adapted to be inserted a pin 9, which enters a socket 10, formed inthe beam and by means of which the cross-bars and links are held inadjusted position with respect to the plow-beam.

It will be observed by referring to the drawings that it makes nodiiference in which direction or position the plow-standards areadjusted they will always be parallel with each other with respect tothe line of draft, and thereby maintain a true parallelism of thetilling tool or implement, such as the culti= vator-shovels,with respectto the line of draft, thereby permitting of the more ready passage ofthe shovel, whereby the plow is rendered of lighter draft.

Various combinations may be efiected by changing the different styles oftilling imple This is obvious to those familiar with this class ofinvention, and a detail description is not thought necessary.

From the foregoing description, taken in connection with theaccompanying drawings,

the construction, mode of operation, and advantages of my invention willbe readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is

In a plow, the combination with the plowbeam; of a forward set ofcross-bars pivoted to the upper and lower sides thereof, a rear set ofcross-bars also pivoted to the upper and lower sides of the plow-beam,links disposed between the ends of the forward set of cross-bars and therear set of cross-bars and pivoted to said cross-bars, bifurcatedplowstandards straddling said links and beam, braces connecting theouter standards to the rear ends of the links, bolts passed through
